One of the most critical environmental problem confronting our nation today is the garbage disposals created by foods. Since the foods garbage contain high rate of moisture, creation of offensive odor and filthy water in garbage fill is now zooming up as the major social problems. Various counter measures have been taken by the government agencies concerned to solve the poignant situation. However, steps taken proved to be rather limited to for the larger restaurants or mass messing facilities while the foods garbage disposal for the individual residential house has been rather ignored. Therefore, this treatise, set aims on the study and analysis described below for the development of rational design and the selection of proposed foods garbage disposer which may be directly available and be operated at individual residential house so that house garbage problems be independently solved. Chapter 1 presents the theory that the decrease of volume of the garbage and transforming into the compost are the best option which is concluded following the analysis of economical aspects over the effects of creation of living garbage and consequent disposal process which effects the environments. Chapter 2 analysed the type of foods garbage disposers and the technical trends of prevailing disposal products in the markets in order to select the type which may be applied to urban residential houses. The needs of such disposers are confirmed through the questionaries distributed to the various housewives directly and collecting answers. Chapter 3 proposes realistic conclusion as to the design of practical, compact sized and soft imaged based on the analysis of trends of house appliances and kitchen interior where proposed disposer should be located. Conjoint analysis is applied for the selection of products concept to maximize the efficiency by the user. As the result, the disposer with price range of 250,000 Korean Won with exchangeable cartridge and the daily disposal capacity of 1 kilogram is selected as the most practically applicable one.

Quercetin production from rutin by a thermostable β-rutinosidase from Pyrococcus furiosus.
Nam, Hyun-Koo,Hong, Seung-Hye,Shin, Kyung-Chul,Oh, Deok-Kun Kluwer Academic Publishers 2012 Biotechnology letters. Vol.34 No.3
<P>Pyrococcus furiosus β-glucosidase converted rutin to quercetin and rutinose disaccharide with a ratio of 1:1, with no glucose, L-rhamnose, and isoquercitrin, indicating that the enzyme is a β-rutinosidase. The specific activity for flavonoid glycosides followed the order of isoquercitrin > quercitrin > rutin. The conversion of rutin to quercetin was optimal at pH 5.0 and 95C in the presence of 0.5% dimethyl sulfoxide with a half-life of 101 h, a k(cat) of 1.6 min(-1), and a K(m) of 0.3 mM. Under the improved conditions, the enzyme produced 6.5 mM quercetin from 10 mM rutin after 150 min, with a molar yield of 65% and a productivity of 2.6 mM/h. This productivity is the highest reported thus far among enzymatic transformations.</P>

Radiotherapy induced colorectal adenocarcinoma with radiation colitis after radiotherapy has been reported as a rare case. A patient with rectal adenocarcinoma as a late complication of pelvic irradiation for gynecological malignancy is reported. A 55-year-old woman with bloody diarrhea for 6 months was admitted. She received radiation therapy for carcinoma of cervix 21 years ago. Colonoscopic findings revealed a polypoid mass on rectosigmoid colon. Histopathologic examination of the polypectomy specimen disclosed adenocarcinoma. We reported herein a case of rectal adenocarcinoma with radiation colitis. The patient who had received pelvic irradiation should have close follow-up with colonoscopic study for the early detection of colorectal cancer.
